Kate already owns 22 necklaces, and additional necklaces are priced at 2 for a dollar. With
$13 to spend on new necklaces, how many total necklaces can Kate own?
If she already has 22 and she can buy 2 for $1 and she has $13, multiply 2 by 13 to get how many she can buy, or 26. Then add the amount she already owns to how many she can buy to get how many she can own, or 48.
